      const applePayRequest: ApplePayJS.ApplePayPaymentRequest = {
        countryCode: 'US',

          type: "final",
          amount: "10.00",
        }
      };

      // Create ApplePaySession
      const session = new ApplePaySession(3, applePayRequest);

      handleEventsForApplePay(session);

      session.begin();
    }
  
  function handleEventsForApplePay(session: ApplePaySession) {

    session.onvalidatemerchant = async (event: ApplePayJS.ApplePayValidateMerchantEvent) => {
      // Call your own server to request a new merchant session.
      const merchantSession = await validateMerchant(event.validationURL);
      if (merchantSession) {
        session.completeMerchantValidation(merchantSession);
      } else {
        console.error("Error during validating merchant");
      }

    };

    session.onpaymentmethodselected = (event: ApplePayJS.ApplePayPaymentMethodSelectedEvent) => {
      // Define ApplePayPaymentMethodUpdate based on the selected payment method.
      // No updates or errors are needed, pass an empty object.
      const update: ApplePayJS.ApplePayPaymentMethodUpdate = {
        newTotal: {
          label: "Merchant Name",
          type: "final",
          amount: "10.00",
        }
      };
      session.completePaymentMethodSelection(update);
    };

    session.onshippingmethodselected = (event: ApplePayJS.ApplePayShippingMethodSelectedEvent) => {
      // Define ApplePayShippingMethodUpdate based on the selected shipping method.
      // No updates or errors are needed, pass an empty object. 
      const update: ApplePayJS.ApplePayShippingMethodUpdate = {
        newTotal: {
          label: "Merchant Name",
          type: "final",
          amount: "10.00",
        }
      };
      session.completeShippingMethodSelection(update);
    };

    session.onshippingcontactselected = (event: ApplePayJS.ApplePayShippingContactSelectedEvent) => {
      // Define ApplePayShippingContactUpdate based on the selected shipping contact.
      const update: ApplePayJS.ApplePayShippingMethodUpdate = {
        newTotal: {
          label: "Merchant Name",

          amount: "10.00",
        }
      };
      session.completeShippingContactSelection(update);
    };


    session.onpaymentauthorized = async (event: ApplePayJS.ApplePayPaymentAuthorizedEvent) => {
      // Define ApplePayPaymentAuthorizationResult
      const paymentData = event.payment;

      if (paymentData.token) {
        // Forward token to your gateway for processing payment and return result to apple pay session
        const result: ApplePayJS.ApplePayPaymentAuthorizationResult = {
          status: ApplePaySession.STATUS_SUCCESS,
        };
        session.completePayment(result);
      } else {
        const result: ApplePayJS.ApplePayPaymentAuthorizationResult = {
          status: ApplePaySession.STATUS_FAILURE,
        };
        session.completePayment(result);
      }
    };


    session.oncancel = (event: ApplePayJS.Event) => {
      console.log("Session Cancelled.");
    };

  }
